Problems solved by technology

However, since lithium batteries contain a large amount of lithium ions in both positive and negative electrodes, safety has become the biggest core issue
Continuous high-current charging will cause the positive and negative electrodes to react insufficiently, causing the battery to heat up naturally, and the limit state will cause an explosion, which will bring serious safety problems

Abstract

The invention provides an SG3525 integrated chip-based single-chip microprocessor control technology charger. The charger comprises an AC (Alternate Current) rectifying circuit module 1, a topological structure circuit module 2, a main output circuit module 3, an output switch device module 4, a battery pack 5, an SG3525 chip module 6, a drive circuit module 7, a constant voltage constant current circuit module 8 and an MCU (Micro Control Unit) detection and control circuit module 9. Charging current and charging voltage can be dynamically adjusted according to the state of charge of a lead acid or lithium battery, current square waves of different frequencies are set, and different pauses, namely intermittent charge, is provided for the battery charging process, so that a novel charger which has the advantages of quick charging, long discharge time of a rechargeable battery, namely high labor, no crystal, no dehydration, no heating and long life is realized.

Description

technical field [0001] The invention relates to a charger with single-chip microcomputer control technology, in particular to a variable-frequency charger which uses a microcontroller as a control device and provides necessary different pauses, that is, intermittent charging, during the battery charging process. Background technique [0002] At present, the batteries on the market are basically divided into two types: lead-acid and lithium batteries, which are used in mobile digital products, electric tools, electric bicycles, electric vehicles, golf carts, and electric buses. How to fully charge the battery quickly, and make the battery discharge for a long time and have a long life is an important symbol for judging the quality of the charger. [0003] For lead-acid batteries, the charging electrochemical reaction equation is: [0004] 2PbSO 4 +2H 2 O+2e=PbO 2 (Positive pole) + Pb (Negative pole) + 2H 2 SO 4 (electrolyte) [0005] The reaction proceeds at the two po...
